There are bores formed in each of two generally cylindrical ends and bushings extend axially upwardly from a nominal face at each of the ends. One of the ends has a bore formed at a radius defined as a first distance. A distance between center points of the bores in the first and second ends is defined as a second distance. The ratio of the second distance to the first distance is greater than or equal to 19.2772 and less than or equal to 19.4125. A valve and method are also disclosed.

Description

BACKGROUND OF THE INVENTION
This application relates to a unique connector link for a butterfly valve.
Butterfly valves are known and are utilized in a number of applications. In general, a butterfly valve sits within a fluid flow duct and pivots between a blocking position and a flow allowing position. An actuator includes a piston which moves a link to pivot a connecting link. The connecting link then moves an arm to, in turn, pivot the butterfly valve within the duct between the restrictive and flow allowing positions.
In the prior art, the connecting link has had some deficiencies.
SUMMARY OF THE INVENTION
A connector link for use in an actuation system for a butterfly valve has a central web extending between two generally cylindrical ends. There are bores formed in each of two generally cylindrical ends and bushings extend axially upwardly from a nominal face at each of the ends. One of the ends has a bore formed at a radius defined as a first distance. A distance between center points of the bores in the first and second ends is defined as a second distance. The ratio of the second distance to the first distance is greater than or equal to 19.2772 and less than or equal to 19.4125. A valve and method are also disclosed.
These and other features may be best understood from the following drawings and specification.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 schematically shows a butterfly valve and actuation system.
FIG. 2 is a side view of a connecting link.
FIG. 3 is a top view.
 DETAILED DESCRIPTION
A butterfly valve and actuation assembly 20 is illustrated in FIG. 1. The valve 22 is positioned within a fluid flow duct 24 and pivots about a central pivot point 26. As known, an arm 28 drives the valve 22 to pivot and is moveable upon movement of a connector link 30. Link 30 has a first end 32 connected to the arm 28 and a second end 34 connected to a piston incorporated into an actuator 36. When a control for the system 20 decides that the butterfly valve 22 should change positions, it drives the piston 35 to, in turn, change the position of the butterfly valve 22.
FIG. 2 is a side view of the connector link 30. As shown, a bushing 31 at the end 32 has a bore 40 with a radius d1. A bushing 31 at second end 34 also has a bore 38. The bore 38 may be formed to the same radius as the bore 40.
As shown in FIG. 3, the bore 40 has a center point c1 spaced from a center point c2 of the bore 38 by a distance d2. In embodiments, d1 is greater than or equal to 0.1583 inch (0.4021 centimeter) and 0.1591 inch (0.4041 centimeter). The d2 distance is greater than or equal to 3.0670 inches (7.7902 centimeters) and 3.0730 inches (7.8054 centimeters).
As shown in FIGS. 2 and 3, the connector link 30 has a central web 40, and the ends 32 and 34, which are generally cylindrical. The bushings 31 extend upwardly at 42, away from each of two opposed sides of a nominal surface area of the outermost portions 46 of the ends, and the web 44.
In embodiments, a ratio of d2 to d1 is between 19.2772 and 19.4125.
One material utilized to form the connector link 30 is 17-7PH stainless steel. The bushings 31 are formed of Stellite 6B®. Stellite 6B® is a cobalt alloy, and is a registered trademark of Kennametal, Inc.
In the prior connecting link, the d1 dimension was 1.568 inches (3.982 centimeters) +/−0.0004 inch (0.0010 centimeter) and the d2 dimension was 3.070 inches (7.797 centimeters) +/−0.003 inch (0.008 cm).
Although an embodiment of this invention has been disclosed, a worker of ordinary skill in this art would recognize that certain modifications would come within the scope of this invention. For that reason, the following claims should be studied to determine the true scope and content of this invention.
